FAR 73.13 — Restricted Area Operations
FAR 73.13 explains restricted area rules: pilots need advance permission from the using or controlling agency before flying inside designated restricted airspace.
FAR 73.13 prohibits operating an aircraft inside a restricted area during its designated altitudes and times unless you have advance permission. Restricted areas exist because hazardous activity — like artillery fire, aerial gunnery, or guided missile testing — may be taking place, and entering one without coordination can be deadly.
To legally enter an active restricted area, you must obtain prior approval from one of two sources:
- The using agency (defined in § 73.15) — typically the military unit or organization conducting operations in the area.
- The controlling agency (defined in § 73.17) — usually the FAA ATC facility that handles airspace release when the area is not actively in use.
Why this matters operationally: Restricted areas on your sectional chart show altitudes and times of designation, but those are only the boundaries — you still need clearance to enter when active. If the area is "cold" (not active), ATC may clear you through. If it's "hot" (active), you must remain clear unless the using agency has authorized your flight.
